The Aussies have the momentum after fighting back to draw the one-dayers 2-2 but the Windies appear to be on a roll.

Nobody gave the West Indies a price of beating Australia in the 50-over series but they came mighty close after Darren Sammy’s heroics on Sunday.

The captain’s amazing knock of 84 from just 50 deliveries almost saw his side home, but they fell just short and had to share the spoils with the Baggy Greens.

But the manner of the defeat was important as it proved that this current Windies’ outfit are here to stay and will not be bullied by the tourists ahead of the T20s and upcoming Test series.

In truth, Sammy and his men have probably played above themselves to date, but the Aussies have not been at their best and are clearly missing captain Michael Clarke.

And so there is every chance that the men from the Caribbean will be able to more than match their opponents with just 20 overs to play with for either side.

They do appear to have players tailor-made for the shortest version of the game and Kieron Pollard has already proved that he is in form with a blistering century in the fourth ODI.

His power suits T20 cricket down to the ground and, in combination with Dwayne Bravo and the returning Dwayne Smith, should provide the islanders with the majority of their runs.

Darren Bravo has yet to fire and looked a bit nervous in the one-day series and maybe the more relaxed atmosphere of a Twenty20 match might see him show his true colours.

Andre Russell has started to blossom and he has also excelled in 20-over cricket in the past and should have a say in proceedings, while the returning Fidel Edwards has given the side a boost and will look to take wickets in both the opening overs and at the death.

It looks a decent Windies side on paper and they do have the trump card of off-spinner Sunil Narine, who has enhanced his reputation over the past few weeks.

The Australia batsmen have yet to work out how to play him and will need to get to grips with the youngster in these two contests.

Australia did not take to Twenty20 cricket when it was first introduced but, after it became apparent that the other nations had embraced the new format, they now put out strong sides with the odd specialist or two.

A new-look Australia will be led by George Bailey after his surprise promotion to the captaincy earlier this year and it will be a similar side to the one that played in the 50-over games.

Shane Watson and David Warner will, once again, be key to their chances and proved that class is permanent after bouncing back to hit half-centuries in the final ODI, while David Hussey will be given licence to thrill..

But it is open to debate as to how strong the Aussie bowling attack actually is and Brett Lee apart, they do seem to have bowlers that could be targeted by the Windies’ big-hitters.

The pressure will be on Bailey, as his appointment as captain was met with some scepticism Down Under and he still has much to prove as a batsman.

Cameron White did not last too long in the skipper’s role and Bailey will need a solid display to ensure that he is the man to lead the Australians to the T20 World Cup later this year.
